Snap the receipt.
Skip the retyping.

That receipt in your truck becomes a cost you can actually find. Gentium reads the vendor, date and exact amount, then suggests the right category. Check it, save it, and keep the original attached.

02 / From the field to your team

See the work.
Not just the text.

Your sub posts an update from the house. The photo, status and time stay with the work—not buried in a group chat.

Know what’s been reported done and what’s still waiting for inspection. The office sees the same record.

From the jobsite to the office

A few things to know

Straight answers.

Can I use Gentium at my desk?

Yes. Open the web app and sign in to work with your houses, files, tasks and costs. Your access depends on your company and project role.

Does AI save the receipt for me?

Gentium reads the document and suggests details and a category. You review them before saving the cost, and the original stays linked to it.

Does an invoice mean the work is done or paid?

No. Recorded cost, payment status, work completion and inspection results are separate records.

Can I choose what a lender sees?

Yes. The lender-sharing screen lets authorized users choose the information included in a read-only report.

Where can I get help or send feedback?

Email an@gentiumconstruction.com or visit our support page.
